DAVIE — Miami Dolphins quarterback Ryan Tannehill seemed to have escaped a Thursday scare, as an MRI did not reveal significant structural damage in his left knee, a league source confirmed to the Palm Beach Post.

Another league source, however, indicated that the team is still gathering information. It's common in situations like this for a player to seek a second medical opinion.

It's also true that the possibility of surgery had not been completely ruled out by the club or player as of Thursday night.

Tannehill crumpled to the ground after sprinting toward the right sideline, in a scene that left players saying after training camp practice that they would be praying for their starting quarterback.

Tannehill opted not to have surgery after injury his left knee last season and instead opted for rehabilitation and stem cell treatment.

Recently, Tannehill made it clear that he was done thinking about and done talking about how his knee was feeling. And it seemed Tannehill was running more often, including on designed roll-outs.

If Tannehill had sustained a significant injury, it would have been the most devastating injury the team could face. The team has confidence in backup Matt Moore, but some believe Miami could be one of the best offenses in the NFL if Tannehill continues his growth under coach Adam Gase.

For now, Moore is poised to take starter snaps as Tannehill's knee is further evaluated.
